HEEL-SPRING.

Specification of Letters Patent.

Patented Sept. 13, 1910.

To all whom it may concern:

Be it known that we, TIMOTHY E. TAY- LOR and JOHN A. THOMAS, citizens of the United States of America, residing at Putnam and Thompson, respectively, in the county of Windham and State of Connecticut, have invented certain new and useful Improvements in Heel-Springs, of which the followingis a specification, reference being had therein to the accompanying drawing.

This invention relates to picker stick operating devices for looms, and the principal object of the same is to provide a novel adjustable cushioning device for the picker stick that will operate the stick notwithstanding the fact that the mounting of the stick may have become defective through Wear or the like, thereby preventing the usual smashes that are incidental to an inoperative stick.

In carrying out the objects of the invention generally stated above, it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in details and structural arrangement-s, one preferred and practical embodiment of which is shown in the accompanying drawmgs, where1n:-

Figure 1 1s a fragmentary new in side elevation of a lay beam of a loom showing the picker stick thereof and the improved adjustable cushioning attachment. Fig. 2 is a detail perspective View of the picker stick, the heel rod and regulating rod, showing their relative arrangements. Fig. 3 is a vertical sectional view taken on the line 3-3, Fig. 1. Fig. 4 is a horizontal sectional View the line 4-4, Fig. 1. Fig. 5 is a fragmentary sectional view taken on the line 55, Fig. 2.

Referring to said accompanying drawings by numerals, 1 designates a lay beam of a loom having the slotted or recessed 2 through which the picker stick 3 rejects and is movable across the same. Said stick 3 is mounted on a laterally projecting stud 4, said stud having a socket 5 in its body and being provided wlth a flattened extension 6 that terminates in a reduced threaded end 7 Said stud is fastened to the usual rocker arm 8 at said flattened extension 6 by the washer 9 and lock nut 10.

Adjacent its lower end, the picker stick 3 is provided with a holding notch 11 that is engaged by the hook-shaped end 12 of the portion.

heel rod 13, said hook shaped end surrounding the forward edge of the stick 3 as shown more clearly in Fig. 4. The foot 14 of the beam 1 has the slotted end 15 of a hanger bearing 16 adjustably and detachably held in engagement therewith by means of the bolt 17 and nut 18, the free end of said hanger being projected outwardly and provided with an opening 19 through which heel rod 13 is slidable. Said rod. 13 extends well beyond the hanger bearing 16 and has a spiral spring 20 coiled therein, the outer end of said spring bearing against an adjusting collar 21 adjustably mounted on heel rod 13. The inner end of said spring bears against a washer 2'2 loose on rod 13.

A regulating rod 23 has one end angularly bent and terminating in an eye 24 that loosely surrounds rod 13 and with which the washer 22 is held in contact by the tension of spring 20. The other end of said regulating rod 23 is preferably pointed and is held in the socket 5 of stud 4 by the pressure exerted upon the end eye 24 by the spring 20.

It will be seen from the foregoin that the tension of spring 20 is constantly exerted to rock the picker stick to the position shown in Fig. 1 of the accompanyin drawings and also to hold the pointed en of the regulating rod 23 in thesocket 5 of stud 4, thereby assuring of the picker stick returning to the position shown after performing its customary shuttle throwing operation, and this automatic return of the stick will be obtained, even though the stud 4 may pzlive become defective through wear or the The spring 20 is preferably formed of high grade, tempered steel wire and is closely wound upon the rod 13 so that if the same should break it would still retain its coiled position about said red.

It will be observed that the outwardly projecting end portion of hanger bearing 16 has its upper surface concaved to provide a seat and guide 25 for the rod 23, which prevents lateral play of said rod.

What we claim as our invention is 1. In a device of the character described, the combination with a picker stick provided with a stud, of a heel rod embracing the lower end portion of said stick, an adjustable sprin coiled about said rod, and a regulating rod having one end slidably engaging said heel rod and its other end held in contact with said stud by the pressure of said spring.

2. In a device of the character described, the combination with the lay beam of a loom and picker stick, a stud on said picker stick having a socket, a heel rod connected with said picker stick, an adjustable hanger depending from said lay beam in which said heel rod is slidably supported, a spring coiled about said heel rod, and a regulating rod having one end resting in the socket of the stud and the other end slidably engaging the heel rod and bearing against said coil spring to press the same, said regulating rod being slidably supported in said adjustable hanger.

3. Ina device of the character described,

a lay beam of a loom, a picker stick, a stud thereon, a heel rod connected at one end to the lower end of said picker stick, a hanger depending from the lay beam in which said heel rod is slidably supported, a coil spring mounted on said heel rod and having one end bearing against a collar, and a regulating rod having one end provided with an eye slidably mounted on said heel rod and bearing against one end of said spring, the other end of said regulating rod bearing against said stud on the picker stick and held in place by the pressure of said spring. In testimony whereof we hereunto aflix our signatures in presence of two witnesses.
